Title

User-Satisfaction Based Differentiated Services For Wireless Data Networks

Abstract

The success of future generation wireless data services will depend on the parameterized provisioning of quality of service (QoS) for applications whose demands and nature are highly heterogeneous. Also, user satisfaction will play a key role in the economic viability of wireless service deployments. In this paper, we present a QoS framework based on the paradigm of traffic class and user satisfaction. The proposed class-based QoS framework comprises a radio resource management scheme which considers user satisfaction based on the perceived QoS, and caters to heterogeneous applications such as voice and multiple types of data services, with diverse QoS requirements. The resource management scheme has two components: the admission control algorithm caters to the long term user satisfaction while the session-based rate and bandwidth allocation scheme manipulates the short term user satisfaction. Performance metrics have been specifically denned for each traffic class - blocking for voice communications, average rate jitter for streaming applications, bounded and negotiated delay for interactive data and background traffic. Extensive simulations using four types of traffic and three classes of users reveal that the proposed framework offer improved QoS without compromising the utilization of the system. © 2005 IEEE.
